ios-swift

To structure a production iOS app, use SwiftUI for declarative interface design and UIKit for imperative controls. Apply practical interop patterns to integrate both frameworks, ensuring maintainable code and smooth UI performance across platforms.

Handle Core Data migrations and performance optimization by applying best practices for data modeling and lifecycle management. Use structured patterns for efficient fetching and persistent store migrations to prevent data loss and maintain app responsiveness.

Prepare an iOS app for App Store submission by configuring privacy declarations, App Tracking Transparency (ATT), and StoreKit. Follow production readiness guidelines to ensure compliance and smooth review when submitting your Swift application.

Yes, you can use SwiftUI interop with UIKit for complex interface design. Apply practical patterns to embed UIKit views and controllers within SwiftUI hierarchies, enabling comprehensive interface building, debugging, and reviewing.

Your iOS app needs performance tuning because inefficient SwiftUI body recalculations and UIKit layout passes cause scrolling jank. Apply performance optimization patterns to identify bottlenecks and ensure smooth rendering across different devices.

You need Core Data for complex data persistence in a Swift iOS app when managing relational data and offline support. It provides structured modeling, migrations, and lifecycle management required for production-grade applications.
